Bring your whole self to work

Pros

Individuality is not only welcomed, it is celebrated. The company focuses strongly on diversity not just of ethnicity, but of age, background, identification, beliefs, and just about anything you can think of! There is a very open and transparent culture, as you can imagine from a company that makes a tool specifically for communication and transparency. Sometimes I find myself so comfortable in my surroundings that I have to actually remind myself that I am, in fact, at work, and need to act as such. But it's just such a friendly and warm atmosphere filled with brilliant and funny people.

Cons

It's a startup, so long hours can be expected if you are not a programmer.

Pros

- The people. The environment is friendly and respectful while still being honest and direct. - There is always the opportunity to work on challenging things. I learn something new every day. - The leadership team is incredibly thoughtful and wise in their decision making and communication. It is inspiring and motivating.

Cons

- In San Francisco, we're currently split between three different offices, all within a block from each other. It works and can be fun to have different offices to visit, but will be more collaborative when we're all under one roof in the near future.
